SPECIFICATION forming part of Letters Patent N 0. 706,825, dated August12, 1902. Application filed January 6, 1902. Serial No. 88,644. (Nomodel.)

To all whom it aw/y concern:

Be itknown thatLWILFORD I-I. HoLsoLAw, a citizen of the UnitedStates,residing at Louis ville, in the county of Jefferson and State ofKentucky, have invented certain new and use ful Improvements inAttachmentsfor Flows; and I do hereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enableothers skilled in the art to which it appertains to make and usethesame. 1

This invention relates to improvements in plows, and more particularlyto'attachments designed to be applied to a walking-plow to transform thesame into a ridingplow or sulky.

One objectin view is the production of such an attachment designed to bereadily applied to any of the common forms of walking-plows and capableof being adjusted to control the depth of furrow; and a further objectis the production, in connection with such attacl1- ing means, of meansfor facilitating the ready adjustment of the traction or carrying wheelsto a wide or narrow gage.

l/Vith these and other objects in view the invention consists, incombination with a plow and a plow-beam, of a suitable axle, meanscarried thereby for securing the said plowbeam transversely thereof, andmeans for adjusting the wheel-carrying ends of said axle to varioushorizontal planes.

It further consists, in combination with the plow and its beam, of anaxle extending transversely to said beam, means for securing said beamand axle together, Wheels carried by the free ends of said axle, meansfor securing a maximum length of bearing between said wheels on theaxle,and means for adjusting said wheels from a minimum to a maximumgage upon the axle.

It also consists in certain other novel constructions, combinations, andarrangement of parts, as will be hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 represents a perspective view ofmy improved attaching means, the plow carried thereby being shown bydotted lines. Fig. 2 represents an enlarged detail view, in top plan, ofthe axle and its attachments. Fig. 3 represents a fragmentarylongitudinal horizontal section through the'squared bearing of the axleand one of the locking-sectors. Fig. 4 represents an enlarged detailView of one of the corner-castings of the axle. Fig. 5 represents asimilar view of the caster and its clamping attachment; and Fig. 6represents a vertical transverse section through the -squared bearingand axle, illustrating in side elevation the clamping means for thesleeve of the locking-sector.

In the art to which the present invention relates it has been founddesirable to provide means whereby a plow of the ordinary walking typemay readily be transformed and employed with facility as a riding-plow,and in the production of such attachments an adjustment of thetraction-wheels to various horizontal planes has been found necessary inorder to accommodate the said Wheels to the contour of the ground beingoperated upon and also tocontrol the depth of furrow. In. order toattain these and other Valuable results, I employ, as willbe seen by thesaid drawings, in connection with any suitable plow, as 1, preferably ofthe double-burster type, having any desirable and well-known form ofbeam 2, a transversely-arranged supporting-axle, as 3, which axle iscomposed of bars 4 and 5, having their inner ends held in contact witheach other and retained in position by means of a squaredtubular bcaring, as G, which incloses said inner ends for a suitable distance. Eachof the rods et and 5 is formed exactly similar to the other, and adescription of one may be applied equally as well to the other, and Iwill therefore describe but one anddesire the description to be appliedto both. The rod is extended horizontally for a suitable distance andcarries upon such horizontal portion an adjustable collar, as 7,provided witha set-screw 8, designed to contact with the outer end'ofhub 9, revolubly mounted upon said horizontal portion forretaining thesame against lateral outward movement, and a sleeve, as 10, providedwith a set-screw 11, engages the inner end of said hub and preventsinwardlateral movement thereof, the said sleev, .being formed withsuitable dust-proof anges, as 12, designed to inclose said inner end ofthe hub. It will be apparent that the set-screws 8 and 11 may be causedto lock the sleeves 7 and at any desired points longitudinalof thehorizontal portion of said bar for controlling the gage of thetraction-wheels carried by the axle 3. At a suitable point intermediatethe length of the bar 4 the same is bent from a horizontal to a verticalplane, as indicated at 13, the said bend being sufficiently great tocause that portion of the bar beyond the point of the bend to extend ina diagonal plane outwardly, and the bar is next formed with acomparatively large bend to bring the inner portion thereof again to ahorizontal plane. It will be seen that by these gooseneck bends withinthe bars 4 and 5 the horizontal portion between the larger bends thereofis given the greatest possible length, while the distance between thesmaller curves 13 is reduced to a minimum and the lower horizontalhub-carrying portion of the bars thereby permitted to have a maximumlength. About the curve 13 is clamped a two-part casting, as 14, each ofthe parts of said casting being made exactly similar to the other,

each being provided With a semicircular notch, as 15, and a secondsemicircular notch 16. Surrounding notch 16 and extending laterallytherefrom is a dust or sand guard flange, as 17, the said flange beingspaced from the notch 15 by an abutting shoulder 18 a distance equal tothe thickness of the inner end of hub 9, whereby when said castings havebeen clamped together by means of bolts, as 1919, about the bend 13, thesemicircular notch 15 surrounding the diagonal portion of the bar andthe notches 16 the horizontal portion thereof, the said hub 9 may bemoved inwardly, the collar 10 having previously been removed from theaxle until its in nerend abuts againstthe shoulder 18 and is guarded byflange 17. Each of the castings 14 is formed with a laterally-extendinglug or car, as 20, apertured, as at 21, for purposes hereinafterdisclosed. It will be apparent that each of the castings 14, as abovesuggested, is formed exactly similar in every respect to the other,whereby an interchange of the castings from one of the bends 13 to theother may be made without the confusion arising from a right and leftcasting with respect to the relative position of the bends. Of course itwill be seen that the statement with reference to the similarity ofthese castings does not apply with reference to their relative positionswhen applied to a particular bend, as the castings of course must bemade in pairs. The notches 15 and the notches 16 of each pair ofcastings are arranged to register with each other, respectively, thecastings being otherwise similar in all respects, and a right castingupon one bend 13 may with facility be employed as a left casting uponthe other bend, and vice versa.

The inner ends of bars 4 and 5 are preferably held in contact with eachother within the squared tube 6, which tube is prepared by forming thesame square and then passing a drill longitudinally therethrough,thereby cutting away portions of its inner wall, as at 22 22, wherebythe rods 4 and 5 may be readily passed within the tube 6 and snugly fittherein. Surrounding either end of the tube 6 is a preferably squaredsleeve, as 23, slotted longitudinally through its under wall, as at 24,and provided with depending lugs 25 upon either side of said slot, abolt, as 26, being passed throughsaid lugs for clamping the sametogether and closing the spaces between slot 24, whereby the sleeve 23is caused to tightly clamp tube 6 and be retained in position. Byreference to Fig. 3 it will be seen that the outer end of the sleeve 23is formed with a circumferential inwardly-extending shoulder, as 23,which fits snugly about its respective bar 4 or 5, the bar carrying alug 51, which is introduced through the slot 24 before the clampingoperation and which engages the shoulder 23 on one side and therespective end of tube 6 on the other, so as to retain its bar againstlongitudinal movement and at the same time permit rotation thereof. Theouter end of the 'sleeve 23 is formed, preferably, with an integralsector, as 27, provided on its periphery with suitable ratchetteeth, as28. Outside of the sectors 27 are arranged operating-levers, as 29, eachprovided with an eye 30, surrounding its respective bar 4 or 5, and anysuitable cotter-pin, as 30, is preferably-passed through the said barfor preventing lateral movement of said eye. Each lever 29 is providedwith a suitable pawl, as 31, designed to engage the teeth 28 of sector27 for locking its respective lever against movement. Any suitablegripping means, as arms 32 32, carried by levers 29, may be connected byrods or otherwise, as is well known, to the pawls 31 for releasing theengagement thereof for permitting movement of the levers. Each lever 29carries an arm, as 33, clamped by means of a bolt, as 34, or otherwisesecured to the same, the lower end of which lever is pivotally connectedwith lug 20 by means of a bolt passed therethrough and through aperture21, whereby movement of lever 29 will operate to raise or lower thelower horizontal portion of the respective bar and to rotate the upperhorizontal portion thereof, the tube 6 and its sleeves 23 and sectors 27being held against rotation by the weight of the plow-beam 2, which beamis clamped between suitable castings 35 35 by means of suitable bolts orin any preferred manner. Each of the castings 35 35 is rigidly clampedto the tube 6 by means of a bolt 36, having its ends passed throughapertures in late rally-extending flanges of the said castings and aboutsaid tube, the ends of said bolt 36 being engaged by nuts which may bethreaded thereon and contact with said lateral flanges for tightly andrigidly clamping the castings 36 in position upon the tube 6.

In order to provide a suitable seat for the driver, a casting 37 isdesigned to be held in position upon beam 2 by means of a clampingbolt38, the said casting carrying any suitable securing means, as bolt 39,for receiving and retaining aspring, as 40, of any suitable form ofseat. I also find it desirable to provide the follower-caster common tomost ridingplows, and inthe production of such I employ any suitablewheel, as 41, revolubly carried between parallel arms 42, the inner endsof which arms are secured to clamped blocks 43 43, which blocks areclamped about a vertical shaft 44 by means of any suitable bolts 45 45,which bolts also retain the arms 42. One of the arms 42 preferablycarries a follower-finger, as 46, designed to free the periphery ofWheel 41 from any foreign substance which may cling thereto. The tubularcasting at 47 surrounds the shaft 44 and permits free rotation thereofand is provided with a laterallyextendingclamping-jaw48. Asecondclamping-jaw, as 49, is preferably loosely carried by the jaw 48, and inoperation the said jaws are designed to be clasped upon either side ofthe rear and lower portion of beam 2 and held in position by anysuitable bolts, as 50 50.

In operation any suitable plow may be transformed into a riding-plowwith any desired gage of its traction-wheels by simply securing its beambetween the clamping-castings 35 and then adjusting the traction-wheelsto the desired gage, as above suggested, upon the axle 3, it beingobvious that the contour of the earths surface operated upon may demandthat one of the traction wheels move in a higher horizontal plane thanthe other, and from the above description it will be seen that theshifting of the levers 29 will produce any desired relative position ofthe said tractionwheels by a sufficient raising or lowering of the lowerhorizontal portions of respective bars 4 and 5.

Among the many advantages of the invention in the present improvedstructure attention might be called to the fact that the bearingssecured by the squared shaft 6 may, if desired, be longer than thedistance between the bends 13 13 through the peculiar gooseneck curvesin the bars 4 and 5, whereby a greater leverage is secured for theraising or lowering of the traction-wheels.
